STATES Mittel SOLOMON GILBERT TOUCI-I'STONE, OF COLUMBIA, SOUTH CAROLIN TENSION FEHLER.

Application ile. May 2, 1924.

To all whom t may concern.'

Be itknown that I, SOLOMON Gr. Tenoris'roNE, a citizen of the United States, residing at Columbia, in the county of Richland and State of South Carolina, have invented a new and useful Tension Feeler, of which the following is a specification.

This invention relates to a tension feeler, which is adapted to be used in connection with slubbers, intermediates, Speeders, roving machines, and other textile machinery.

in the operation ol' machines of this class, it sometimes happens that the contact gears or changing devices get out of order, or from atmospheric changes, or through the tampering with the tensioning devices by unskilled help, the ends of the sliver become tighter that desired, resulting in unevenv or weak roving, thereby causing uneven or weak yarn to be produced.

The general object of the present invention is to provide improved automatic means for preventing this undesirable result, which is in the forms of an attachmentadaptedto shift the shipper rod, Vand to stop and lock the machine whenever the tension becomes too tight, so that it is impossible to operate the machine until the tension has been properly adjusted.' The invention is in the form of a feeler over which the sliver is d awn, and which may be readily attached to any of the machines now in use without any material alteration in the latter. Y

The specific construction of the invention and its application to textile machinery will be more particularly described in connection with the accompanying drawings, which illustrate the invention in its preferred form.

Figure 7 is a perspective view of the feeler detached.

Figure 8 is a4 perspective view of the latch-engaging trip linger.

Figure 9 is a detail view of the feeler bar.

For the salie of illustrating the application of the invention to the textile art, I have shown it in connection with a roving machine of common construction, the machine being shown somewhat diagrammatically, and only those parts being shown which are necessary to a full understanding of the invention The roll beam of the machine is denoted by the numeral 10, and the second and third samsons by the numerals 11 and 12, respectively. Top and bottom cones 13 and 14 are carried by shafts 15V and 16, which are suitably joiurnaleid in the frame of the machine, and may be driven in the usual manner. The cones 13 and 14: are connected by a belt 17, which is embraced bya fork 18 carried at the end of a bar 19, which in machines of this character is advanced longitudinally to vary the speed of the spindles.

rlhe roving machine also includes a vertically reciprocating frame 20, one end of which is shown in Figure 1, guided on the track 21, and actuated by a rack 22 in mesh with a pinion 23 on the shaft 1G. rThe end of the frame 2O is counterbalanced by weight 24 attached to a chain 25, which passes over sheaves 26 mounted on the samson and under a sheave 27 mounted on the slidable frame, and has its end secured to the frame, as indicated at 28.

A shipper rod 3G, shown in Figure 3, is adapted to be moved longitudinally in the direction indicated by the arrow for thrcwing the machine out of operation. rlhis. shipper rod passes through an eye 3l formed on the upwardly extending arm of a swing lever 32, and has a stop or tappei 33 secured thereto, and normally in` engagement with the swing lever, as shown in Figure 3, during the operation of the machine. The swing lever 32 is fulcrumed on a stud 3a, which is mounted in a bracket 35 secured to the beam 10. The lever has a laterally extending arm 36 to which is adjustably secured a Weight 37, which is su-` cient to swing the lever 32 and the shipper rod 30 longitudinallv,and render the machine inoperative. *The lever, lioweveniis normally held with the arm 36 raised by means of a latch 38 pivoted to theilower" end of the lever,'andfhaving anotchedend 39 adapted to project through and engageY a stop plate l0 secured to the samsontl" A t-appet or knock-oit 4l is, however, se-

cured to the bar 19, and whenV the har reaches machine tout of operation, only lat the 'con-i clusionof Ythe"rovii'ig operation. TheV pres'- ent invention, however, provides` supplef mentary means for automatically releasing the latch 38l` to permitmovement` of the shipperrrod, `whenever the tension of the* sliver loe'comes greaterlthan thatli'or which thehinachine set, thereby makingfurther operationfof the machine impossible until the't'enlsiii ot thev machine is adjusted, and consequently)'making it'iinpossihle to lprow duce an inferior, 'uneven yarn.
